High frequency electrical connector

Abstract

An electrical connector with an insulative housing and a plurality of contacts retained thereto. The housing includes a base and a tongue extending forwardly from the base. Each first contact includes, along the front-to-back direction perpendicular to the transverse direction, a front first contacting section, exposed above a mating face of the tongue, a rear first soldering section extending out of the housing, and a first connecting section located therebetween wherein in the pair of first different contacts, the first connecting sections are transversely offset from the corresponding first contacting sections and toward each other so as to have therebetween a distance, in the transverse direction, smaller than that between the corresponding first contacting sections.

What is claimed is: 
     
       1. An electrical connector comprising:
 an insulative housing including a base and a tongue extend forwardly from the base in a front-to-back direction, the tongue forming a mating face; 
 a plurality of first contacts retained to the housing in one row along a transverse direction perpendicular to the front-to-back direction, each of said fist contacts including, along the front-to-back direction, a first contacting section, a first soldering section and a first connecting section therebetween; 
 a plurality of second contacts retained to the housing in another row along the transverse direction, each of the second contacts including, along the front-to-back direction, a second contacting section, a second soldering section and a second connecting section therebetween; 
 the first connecting sections being spaced from the second connecting sections in a vertical direction perpendicular to both the front-to-back direction and the transverse direction while the first contacting sections and the second contacting sections being commonly exposed upon the mating face; 
 the first contacts including a pair of first differential contacts and a first power contact and a first grounding contact located by two sides of the pair of first different contacts in the transverse direction; and 
 the second contacts including a second grounding contact and two pairs of second differential contacts located by two sides of the second grounding contact in the transverse direction; wherein 
 in the pair of first differential contacts, a pitch (D 1 ) defined between the first contacting sections is larger than a pitch (D 2 ) defined between the first connecting sections, and in the pair of second differential contacts, a pitch (D 1 ′) defined between the second contacting sections is larger than a pitch (D 2 ′) defined between the second connecting sections so as to increase a distance (d 4 ) between the pair of first differential contacts and the pair of second differential contacts in the transverse direction in a top view along the vertical direction. 
 
     
     
       2. The electrical connector as claimed in  claim 1 , wherein said distance (d 4 ) is 1.64 mm. 
     
     
       3. The electrical connector as claimed in  claim 1 , wherein in the pair of first differential contacts, the first connecting section includes a first offsetting section linked to the corresponding first contacting section so as to result in a pitch change between the first contacting sections and the first connecting sections, and in the pair of second differential contacts, the second connecting section includes a second offsetting section closer to the corresponding second contacting section as to result in another pitch change between the second contacting sections and the second connecting sections. 
     
     
       4. The electrical connector as claimed in  claim 3 , wherein in the pair of first differential contacts, the first offsetting sections of the first connecting sections extend toward each other in the transverse direction so as to reduce the corresponding pitch (D 2 ); in the pair of second differential contacts, the second offsetting sections of the second connecting sections extend toward each other in the transverse direction so as to reduce the corresponding pitch (D 2 ′). 
     
     
       5. The electrical connector as claimed in  claim 4 , wherein the first connecting section further includes an oblique section linked to the corresponding first offsetting section, and a first horizontal section linked between the first oblique section and the first soldering section. 
     
     
       6. The electrical connector as claimed in  claim 3 , wherein the pitch (D 2 ) of the pair of first differential contacts is 1.5 mm. 
     
     
       7. The electrical connector as claimed in  claim 3 , wherein the second connecting section further includes a reduced section linked between the second contacting section and the second offsetting section. 
     
     
       8. The electrical connector as claimed in  claim 7 , wherein a space ( 5 ) is formed between the two reduced sections of the pair of second differential contacts to receive the first contacting section of the corresponding first power contact or the first grounding contact. 
     
     
       9. The electrical connector as claimed in  claim 1 , wherein the second connecting section of the second grounding contact defines a width (d 1 ) which is larger than a distance (d 2 ) defined between two opposite outermost edges of the first connecting sections of the pair of first differential contacts so as to full cover the pair of first differential contacts in the vertical direction. 
     
     
       10. The electrical connector as claimed in  claim 9 , wherein the width (d 1 ) of the second connection section of the second grounding contact is 3.1 mm. 
     
     
       11. The electrical connector as claimed in  claim 1 , wherein the pitch (D 1 ) of the first contacting sections of the pair of first differential contacts is same with another pitch (D 3 ) of the first soldering sections. 
     
     
       12. The electrical connector as claimed in  claim 1 , further including a first seat to position the first soldering sections, and a second seat to position the second soldering sections, wherein the housing includes an engaging slot to secure the first seat, and an engaging part to secure the second seat. 
     
     
       13. The electrical connector as claimed in  claim 12 , wherein at least one of the first seat and the second seat is configured to be assembled to the housing upwardly in the vertical direction. 
     
     
       14. The electrical connector as claimed in  claim 1 , wherein the first connecting sections are positioned below the second connecting sections in the vertical direction.
